ART OF SHEET FILING.

Application filed August 4, 1923.

This invention relates to improvements in the art of sheet-piling such as is frequently used in forming the sides of coder-dams, dikes, bulkheads, earth or water retaining walls, and the like. By the use of my in vention, strong, durable sheet-piling may be quickly and cheaply constructed which, when completed, forms practically a continuone wall impervious to water. Other fea- 3 tures and advantages, and the details of my invention will be fully understood by referring to the following specification and accompanying drawings.

In that form of device embodying the features of my invention, shown in the accompanying drawings,

As shown in the drawings, 20, indicate piles which are here shown as made of 0011-, crete and provided with longitudinal holes 21 to accommodate jets which may be used to assist in placing thepiles to form the sheeting. Each of the piles 20 is provided at one edge with a groove 22, and at its other edge with a ridge 23 provided with a concave groove 24:. As shown, the ridge 23 is adapted to fit into: the groove of an adjacent pile when the sheeting is formed so that. there will be left between ea h two Serial No. 655,627.

After the piles are in place, the channel 25 and any cracks that there may be between the edges of the piles, as indicated by 26, are grouted in the following manner to bond the piles together. I provide a bonding gun which comprises, in general, a hopper 27 adapted to contain a charge of grout and a cylindrical barrel 28 for conducting the grout from the hopper into the channel 25.

The gun may be supported in any eonvenient manner so that it may be moved into various positions for use, and any eonvenient means may be provided for raising and lowering thesame. I have here shown the supporting means as including boom '23 of any suitable derrick or hoist and a hoisting cable 30 attached to the hopper, as

piles, a channel 25 circular in cross shown. The hopper 27 is substantially cy-..

lindrical in form and provided with a tight cover 31 which may be fastened down in any suitable manner. The hopper is large enough to contain a charge of grout sufficient to fill one or more of the channels 25 and still provide an air space at the top. Communication is afiorded to this air space through the pipe 32 to which is attached a pressure hose 33. Any suitable means is provided for introducing compressed air through the pipe 32 into the top of the hopper so that grout will be forced therefrom through the barrel 28 under pressure.

Means are provided for shutting off the flow of grout from the hopper into the barrel when desired. Such means comprise a pair of gates 34 pivoted at 35, as shown. In Figure 5, these gates are shown in their closed position in solid lines, and in their opened position in brokenlines. The two gates are mounted on the transverse pivoted shafts 35 having on their front ends the intermeshing segmental gears 36. One of the shafts 35 carries on its end the arm 37 to which is attached the operating lever 38 provided with a detent 39 and quadrant 40. When the lever 38 is in the position shown in Figure 4: with the detent 39 engaged in the notch in the quadrant, the gates are closed. An operating cord 41 is provided so that when this cord is pulled it will move the operating lever 38 to the left (as viewed in Figure 4:) to the position shown in Figure 4 to close the gates and stop the further discharge of grout. When thelever reaches this position, the detent 39 forced by the spring 39 engages the notch in the quadrant and thus holds the gates closed.

The upper end of the barrel of the'gun is provided with funnel shaped, or flared member, into which the lower end or the hopper fits. The spout 51 at the lower end of the hopper is beveled, as indicated at in order to make a snug fit with the tunnel 50 when it is forced down into the same. The following means are provided for holding the spout 51 snugly inside of the tunnel 50. Mounted on the hopper a short distance above the gate mechanism is a circular ring or shelf 55 adapted to be engaged by four hooks 56 which are pivoted to the upper edge of the tunnel shaped member 50, as shown.

Each of these hooks 56 i provided with a downwardly projecting arm 5? and a small spring 58 operating to yieldingly hold the hooks in position in engagement witn the ring 55. There is also provided a rotatable cam ring 59 held by suitable supporting means 60. This cam ring 59 is formed so that when it is in the position shown in Figures 7 and 8, the hooks 56 will be in engagement with the shelf 55. The cam ring, however, may be rotated by means of the operating handle 59 to cause its widened parts to engage with the arms to force them inwardly and thus disengage the hooks 56 from the ring 55 to permit the hopper to be withdrawn from the flared member 50.

A flexible connection is arranged at the upper end of the barrel of the gun to permit the requisite twisting and bending movements between the hopper and the barrel. This flexible connection comprises, in general, a flexible hose or tube 60" wiich may be made of canvas, rubber, fabric, or other suitable material. The upper end of the flexible tube 60 is clamped on to the lower end or spout 50 of the funnel shaped member 50 bymeans of the clamp ring 61; and its lower'end is inserted in the upper end i the barrel 28. The upper end of the barrel 28 is provided with a clamp ring 62 similar to the ring 61, and these two rings are connected by six bars 63 having round balls 6% at their ends. The rings 61 and 62 are provided with flanges 65 and 66, respectively. Each of these flanges has formed in it 51X hemispherically shaped sockets adapted to accommodate the balls 64. The fiaiiges 65 and 66 have bolted'to them two rings '68 and 69, respectively, each having six hemispherically shaped recesses actwith the recesses 1n the rings 65 and 66 to form sockets to accommodate-the balls G l on theins'ertion of the bars. Thecompleted "nel andcrachs and crevices will be adapted to co-' the rods 63. The recesses in-the rings 68 and 69 are providedwit-h radial slots 'to permit recesses in the rings 68 and 69, through which the bars 63 pass are sufiiciently large to permit twisting and movement of the same therein. By means of this construction, the bars will take tensile and compression strain between the hopper and the barrel oi the gun and still permit sui'licient twisting andbending movement between these members.

In the practice 0]": my invention, the piles 20 are driven or placed in position as shown, to leave the channels 25 between. The hopper of the gun is then filled with concrete nearly to the top with the gates closed. The cap member 70 is then pressed into the bottom of thebarrel 28. The barrel of the gun is then lowered intoone of the channels 25. The cap member "Z0 prevents any water or other material that might be in the channel fromrgoing up into the barrel of the gun. The lowering of the barrel with this cap member on the end servestherei'ore to displace any water that there may be in the channel. It will be noted that the barrel has a cross sectional area substantiallythe same as the cross section of the channel 25. In other words, the barrel. substantially fills the channel. There is suliicient space, however, between the'barrel and the channel to permit any water to escape that there might be in the channel. Such water oozes up around the sides of the barrel as it is lowered or else escapes through the cracks hen the barrel reaches the bottom of the channel, compressed air is introduced into the top of the hopper through the pipe 32 to the desired pressure, and the gates 34: at the bottom of the hopper are then opened, permitting the grout 72 to be discharged from the hopper through the barrel into the channel. The pressure of the grout is sufficient to remove the cap member. 70 from the end of the barrel. This member is pref erably formed out of sheet metal and remains at the bottom of the channel; a new member being provided for each channel. It is obvious that the air pressure and the weight of the column of grout causes the grout to issue from the mouth of the barrel with con siderable pressure, 50' that the channel itself and the cracks, such as 26, around it, are completely filled with grout under pressure. As the grout issues from the mouth of the barrel, the barrel is withdrawn, the speed of withdrawal being timed so that the chancompletely filled.

If desired, a reentorcingbar, such as indicated by 73,in Fig. 3, maybeplaced in the channel 25. hen it is desiredxtouse such a reentercing bar, I prefer toseparate the barrel of theun from the hopper and lower it into'the channel 25-with its cap member 70.- I then insert'the reenforcing bar "73 into the barrel, and. then joinlthe liopper onto the barrel by means of the hooks 56. The grout is then discharged in the usual manner to remove the cap 70 and fill the channel, the barrel being withdrawn as the grout is discharged. The reenforcing member 73 remains in the channel surrounded by grout.

WVhile I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in Which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.
